Smooth (not found, should be a basic answer)

Hello,
I'm working with the student version of MATLAB R2012a, I am still new to the world of MATLAB so this may seem very basic. Right now I have a macro that deals with the "smooth" function. Here's part of the code in the macro:
g=fy(:,2);
sg=smooth(g); %5 point moving average
The %5 portion is a comment, not actual code. I am getting an error of:
Undefined function 'smooth' for input arguments of type 'double'.
The macros I have work fine on the lab computers at my university but they have a bunch of different toolboxes installed. What toolbox has this function so I can buy it and put it on my personal computer? If it's not in a toolbox, where do I obtain it?
Thank you,

Maybe it's this official MATLAB function: http://www.mathworks.com/help/curvefit/smooth.html in the Curve Fitting Toolbox. Or maybe it's something that some one custom wrote but is not included on your computer for some reason.

Paul, type "ver" at the command prompt to list all the toolboxes that you are able to use.
